- Install yaml-cpp:
- Download the latest release of yaml-cpp from the official website.
- Extract the downloaded file to a desired location.
- Open a command prompt/terminal and navigate to the extracted folder.
- Type "cmake -G "Unix Makefiles" -DYAMLCPPBUILDTESTS=OFF -DYAMLCPPBUILDCONTRIB=OFF" and hit enter.
Type "make" and hit enter to build the library.
Create a C++Builder project.
- Open C++Builder and create a new Console Application project.
Right-click on the project and select "Add > New > Unit" to add a new unit to the project.
Add the yaml-cpp library to the project:
- In the "Project Manager" window, right-click on the project and select "Add > Existing item".
- Navigate to the folder where you extracted the yaml-cpp library and select the "include" folder.
Click "Add" and repeat the process for the "libyaml-cpp.a" file in the "lib" folder.
Include the yaml-cpp library in the code:
- In the new unit you created, add #include <yaml-cpp yaml.h=""> at the top of the file to include the yaml-cpp library.
Use the YAML::LoadFile("file.yaml") function to read in a YAML file and store its contents in a YAML::Node object.
Access the YAML data:
- Use the "[]" operator to access the data stored in the YAML::Node object.
- The data is stored as a map, so you can use the key to access the associated value.
Example code:
include <yaml-cpp yaml.h="">
int main() {
// Load the YAML file into a YAML::Node object
YAML::Node config = YAML::LoadFile("config.yaml");
// Access a specific value in the YAML file
int port = config["Server"]["Port"].as<int>();
// Print the value
std::cout << "Server port: " << port << std::endl;
return 0;
}
